What Can You Change Dae Files Into for Upload Into Sl
So i started this listing here:
Where is the log ?
This is probably one of the most asked questions in this context. Why not identify the error letters into a popup window ? So where IS the log ? Mine is at:
C:\Users\myLoginName\AppData\Roaming\SecondLife\logs\SecondLife.log
Where is yours ? I am sure y'all will find it quickly and easily :matte-motes-evil:
Missing weight groups
When a weight group is missing, the GUI reports ... cypher. Hither is what you find in the log:
Asset did not comprise the joint (if you're u/l a fully rigged asset w/joint positions - it is required).mFootRight
Asset did non contain the joint (if you're u/l a fully rigged asset west/joint positions - it is required).mFootRight
That looks a bit similar a wrong formatted message. But ok, i can gauge mFootRight is missing... Mayhap i curt information about "Weightgroup mFootRight does not exist" would exist more than helpfull here. Only some questions heighten:
- what has a weight group to exercise with joints positions? In that location is no rig in that particular collada file, and no joints positions...
- And why does a missing joint disable uploading of the mesh when i practise not desire to upload joints at all ?
- And why does this issue not popup equally error in the GUI ? just the weight selection is greyed out without explanations.
Gear up: Add an empty weight grouping of name "mFootRight" to your mesh, then try over again.
Unweighted vertices
When a vertex is non weighted, the GUI tells:
Error: Dae parsing effect - see log for details.
Here is the log:
verifyCount: Error: (expected/got)2233/2232verts
Why not only: 1 out of 2233 vertices is not assigned to whatever weight group. Delight check your weighting.
Fix: Find the missing vertices, assign them to at least one existing weight grouping, and try again.
Vertices weighted to more than iv bones
Recently i had the impression that sometimes the SL Importer disables "with weights" when the model contains vertices with more than than 4 weights. There is indeed a limitation in 2d Life that allowd no more than four os weights per vertex.
LL has mentioned (long time ago) that they do non test this constraint. So it might actually be no isse, but probably it is good to remember this constraint anyways.
Vertices weighted to 0.0
I accept the impression that sometimes vertices which are weighted to 0.0 create spikes in SL. I believe that this is not a general upshot. The i instance where i have seen this problem was where all weights had a value of near to 0 and 2 of the weights had value of 0.0 It may be worthwhile to clean meshes with 0,0 weights. But be aware that every vertex needs at least one weight. Otherwise the SL Importer refuses to import the mesh.
Wrong selection of objects
I frequently forget to enable the "option only" checkmark in the Collada exporter in Blender. This can lead to a whole bunch of bug with the SL Importer depending on what is in your scene. I accept more often than not seen parsing errors and "no mesh independent in data" errors in this case.
MAV_BLOCK missing
The trouble is with the material assignments. When y'all have multiple materials, sometimes yous tin find a configuration where the entire set up of faces for material A uses simply vertices which are likewise needed to form the faces for Material B. Look at this cube:
The iv narrow sides are all assigned to the red material, the large sides are assigned to yellowish material. You encounter that the red fabric and the yellowish cloth use the exact same set up of vertices.
Maybe the vertex ready is actually only exported once, but assigned to both materials. Actually i was able to reproduce the upload problem on the Firestorm viewer only. On the V3 from Linden Labs the trouble did not appear.
Workaround: Add one extra triangle and assign it to ane of the materials. Now the vertex sets are different, and the SL Importer (firestorm) is happy.
And finally: "MAV = Textile Nugget Value" (as i learned from a more than contempo post in this thread)
Duplicate vertices
Sometimes the SL Importer is non able to create lower LOD'south. Typically you lot see either that all lower LOD vertex counts are identical to the highest LOD regardless what limits you type in. Sometimes the viewer even crashes. And sometimes everything messes up when you add together a physics shape with duplicate vertices.
Workaround: Always ensure that your model does not contain duplicate vertices.
To be continued (while stumbling over more than problems)
